Self-Balancing robot project starts!

I just had an idea yesterday that can get me to make a self-balancing robot without buying any expensive electronic components.
You know last summer i made a cellphone controlled RC Car which had a tabletpc onboard to get commands via bluetooth.That time , having an onboard tabletpc , save me from buying a bluetooth chip which costs about 60$.This time, to make a self-balancing robot i’ll have to have whether an Accelerometer or a MEMS Gyro to track rotation of the robot.
Those sensors are pretty expensive too.So i’m thinkin about putting my n95 smartphone onto the robot.As i have Accelerometer on the smartphone i can use it to measure rotation movement of the robot.

I tried to explain how it is going to work in the photo.

And the finished robot will look something like this:

 

What I’ve been working on so far…

Hi my fellow readers,
Here’s a little summary of the projects i’ve been working on lately…
Algoritms&Programming 2 Homework :: OpenCV Character Position Detection :
With OpenCV’s built-in Computer Vision Functions it has been very easy to develop a character position detection application.
Here is a screenshot from the application i made.


Algoritms&Programming 2 Homework :: OpenGL 2D Drawing & Mouse Input Handling with GLUT
Last week we were asked to make a simple application , using OpenGL & GLUT , that draws a 2d house and movable circle onto the screen.But that’s no fun for a real programmer.So i decided to make it a little bit fancy.Here what i’ve done.
I made a movable head instead of a circle and added hair.And i implemented a relation between hairs & mouse movement.If mouse moves more than a pixel at a render cycle.It calculates the projection of mouse movement on X & Y axis’ and uses those values to create a wind like effect on hairs.
I also implemented a relation between movement of the head and orientation of grasses.I also used the distance value , between head and each grass , which is already calculated to set color the color of each individual grass.As you move head closer to lawn it brights up the grasses with inverse propotional relation between h labelled distance and Green color value of the grasses.
Personal Interest :: Comet Programming with ORBITED & TWISTED

Narduino & IR-Liqard Appearance on Make:Blog

Hi fellows,
It’s been quite a while since these projects first appeared on Make:Blog but i didnt share those on my blog.So i decided to have them on my blog. :)

LunarCannon Project Demo

hi fellows,
I’ve been working on a web app. project which lead me to use RaphaelJS library 5 months ago.Last night i just wanted to do something with this library just for fun other than business.So here is another Gravitation Involved Project :D .
Use Arrow Keys to rotate Cannon
And Space Key to shoot

let me know your reviews :)

to Sum Up

Hi my fellow readers ,
It has been a long long time… I just wanted to sum up what i have been up to lately…
I have been pretty busy with a big web-app project based mainly on javascript.I am also working on some other web programming projects. As i spent months of coding with javascript – with the help of jQuery – and PHP , i can barely tell the only limit is imagination from now on :) :P and the capabilities of the browser off-course :D

Well… off course i didn’t spend all my time on web-development , i have been studying OpenCV with OReilly’s book called ‘Learning OpenCV’. It’s a quite complicated library but it’s still the simpliest way to do Computer Vision. But with the entertaining and creative apps & softwares that are made possible with Computer Vision technology , i dont care how hard or how much of time consuming it is.

NarDuino 2.0 !!

Hi my fellow readers,
Today, i’ve been working on re-building my NarDuino car project all day . So why am i rebuilding it?. Because i decided to rebuild the motor driver ,that i’ve used on narduino, onto a veroboard so i can use it later on other motor controlling involved projects. It has been quite an hard thing to do since i have no experience at soldering at all. But i just started and finished it.

DIY IrReceiver Project

hi fellows,

Here i made another project with my brandnew arduino demilanove.In this project i intended to send commands to my laptop computer with an infrared remote controller.I used an old ir receiver that came within video card of my old computer.I also choosed to use its own remote controller to send ir signals.It turned out to be very useful.I wrote a very simple code with python which you can add more responses for different ir signals.
